		<title>Geographical filtering & sorting with Lucene</title>
	</head>
	<body>
		<p>
			This package makes it possible to filter and sort according to
			geographical constraints.  For example, filter to include only
			restaurants within 2 miles of a specified latitude/longitude, sorting
			by distance ascending.
		</p>
		<p>
			See <a href="http://www.nsshutdown.com/projects/lucene/whitepaper/locallucene_v2.html">here</a>
			for details on the technical approach.
		</p>
		<p>
			Unfortunately, this package is still very new, and has little to no
			documentation.  It's best to look at the unit tests included in
			the source distribution.
